HENRY A. DIRKES, OF NEW YORK, N. Y.

VENTILATOR.

Application filed December 28, 1908, Serial No. 69,731.

To all whom it'moy concern:

Be it known that I, HENRY A. Dumas, a citizen of the United States, and a resident of the city, county, and State of New York, have invented certain Improvements in Ventilators, of which the following is a specification.

This invention relates to certain improvements in ventilators, and more particularly in that class of such devices which are particularly designed and adapted for location at the windows of buildings, cars or the like for permitting the escape of foul or vitiated air therefrom, and the object of the invention is to provide a device of this character of a simple and comparatively inexpensive nature and of a compact structure, which shall be capable of ready application to such windows or other openings without presenting an unsightly appearance, and which shall be adapted to facilitate the escape of such foul or vitiated air, and at the same time to effectually exclude the entry of rain or cold air into the room and thereby prevent drafts and damage such as might be caused by such entry.

The invention consists in certain novel features of the construction, and combinations and arrangements of the several parts of the improved ventilating device, whereby certain important advantages are attained, and the device is rendered simpler, less expensive, and otherwise better adapted and more convenient for use, all as will be hereinafter fully set forth.

The novel features of the invention will be carefully defined in the claims.

In the accompanying drawings which serve to illustrate my invention Figure 1 is a perspective view showing a ventilating device embodying my improvements applied in position for use at the outside of the upper part of a window; F ig. 2 is a top or plan view of the improve ventilating device detached from the window; Fig. 3 is a sectional view taken transversely through the upper part of a window and showing the ventilating device embodying my improvements applied in position for use; Fig. 4 is a fragmentary perspective view illustrating a modified formation of the improved ven- Specification of Letters Patent.

tilating device; Fig. 5 is a view similar to F 1g. 3, but illustratlng the application of the device shown in Fig. 4, to the window, and

\Fig. 6 is a view somewhat similar to Figs.

3 and 5, but showing another modified formation of the improved ventilating device.

The drawings show certain features forming no special part of the present invention and are not therefore specifically claimed. Attention is directed to my copending application, No. 544,730, filed February 19, 1910. I

As shown in Figs. 1, 2 and 3, the improved ventilating device is constructed from two similar elongated parts or members 2, 2, which are overlapped and fitted to slide one upon the other at the central part of the device, as shown at 3, so that when the device is extended transversely across the upper part of the window, said parts or members 2, 2 may be adjusted longitudinally with reference to each other in order to permit of accommodating the device to windows of different widths. As herein shown, the parts or members are formed from sheet metal, but this is immaterial to my invention and wood or other desired material may be substituted at will for metal in the manufacture of the device. The ends of the parts or members 2, 2 of the device are closed by end plates 4, 4 arranged at opposite ends of the device and adapted to be fitted flush upon the inner surfaces of the stiles of the window casing 1, and as herein shown, these end plates are adapted to receive attaching devices which are herein represented in the form of screws (5, 6 having engagement with slotted openings 7, 7 extended horizontally in the inner parts of said end plates, the tips of said screws being adapted to be engaged with the stiles of the casing 1, in such a manner as to effectively support the improved ventilating device in position extended transversely across the window. The upper edge portions 5, 5 of the parts or members 2, 2 of the improved ventilating device are also shown herein as horizontally directed so as to be adapted to be extended within the window casing 1 and fitted flush against the upper bead thereof, and said invardly extended edge portions 5, 5 are also provided on, and this construction serves to producewith horizontally directed slotted openings 6, 6 similar to the slotted openings 6, 6 at the end plates 4, 4- and adapted to receive screws or like fastenings by meansof which the improved ventilating device is adapted to be securely supported along its upper part upon the casing of the window or other opening to which it is applied. By this construction it will be seen that the improved ventilating device is adapted to be supportedyas shown in Figs. 1 and 2 in position extended transversely across the upper part of the window casing at the outer side thereof, so as'to stand in position'to effectively shield the opening produced across the top of-the window when the upper sash is lowered and its upper rail 10 is separated from the top of the casing, wherebyit will be seen that ;the entry of rain, snow, dustor the like into the building to whichthe device is applied is effectively prevented. The body portion of each part or section'2, 2 or that portion thereof which is downwardly extended across the upper part of the window opening adjacent to the top ofthe casing 1, is downwardly and outwardly curved or inclined, as clearly shown at 8, so as to shed the rain, snow or the like falling therewithin the said body portion a space or chamber 9, located at the outside of the room but in communication with the interior thereof when the upper sash is lowered, in which chamber the warmer and foul or vitiated air at the upper part of the room is adapted to be received and subjected to a certain cooling preparatory to its discharge,

from the room as will be hereinafter ex plained. Below the outwardly and down-v wardly curved body portions 8, 8, the parts or members 2, 2 of the improved ventilating device are provided with deflecting surfaces 10, 10 which are inclined downwardly and inwardly toward the structure to which the device is applied, and. which have their.

lower edge portions spaced away from the outer surface of the upper rail 10 of the upper sash of the window .in such a manneras to produce a narrow elongated outlet port,

or vent 11 communicating with the lower part of the space or'cliamber 9, and at which the foul or vitiated air supplied to said chamber or space from the room through the'opening produced by the lowering of the upper sash, is adapted to be dischargedinto the external air. The space 11 aflorded between the sash. rail 10 and the lower edges of the deflectors 10, 10 of the members 2, 2 will usually be quite narrow to 'afiord the best results, but the width of said space or outlet port ll may be'convenientl varied, while the serews or fastenings 7 are loosened, the members being securely held in position when properly adjusted; proper manipulation of such screws or fas tenings 7, 7. It may be here stated that the arrangement of the screws or other fastenings as herein shown, so as to be accessiblefrom the interior of the building affords a material advantage in the installation of the improved ventilating device and permits of much greater convenience in the adjustment of the same'in position for use. By the construction and arrangement of the improvedventilating device with the inclined deflecting surfaces 10, 10 immediately above the outlet port or vent 11, whereat the foul or vitiated air escapes from the space vor chamber 9-, itwill be seen that such air as may be moving outside the building to which the device is applied will, upon contact with such surfaces, be deflected down-' wardly so as to flow across the outlet port or opening 11 and thereby exert a certain suction tending to accelerate the discharge of the foul or vitiated air. at such outlet port or vent 11, the external air being-at the same time prevented from entering at said port or vent 11, sothat drafts caused by the admission of the cold external air at the upper part of the room are effectively avoided. In the drawings I have also shown the end plates 4:, t provided with projecting exten.-. sions or shields 12, 12 which are outwardly and downwardly directed at the ends of the outlet port or vent 11 in such a manner as to prevent'the entry of sudden gusts or cross drafts of air such as might occasionally penetrate into the chamber or space 9 and interfere to an extent with the proper discharge of the foul or vitiated air therefrom. Where desired these shields may evidently be made larger than herein shown.

In Figs. 4 and 5, I have shown the improved ventilating device constructed in a simple piece, instead of in two slidably related parts ormembers, and Ihave'also illustrated the employIrTnt'of means comprised in my invention for permitting desirable adjustment'or regulation of the width of the outlet port or vent '11. ,As'herein shown the inclined deflecting portion 10 of the device is slotted at 16 for the passage of screws 15 carried by a regulating member or valve 14:,

which is made in the form of a flat elongated strip, fitted flush upon the surface'of the def fleeting portion 10 within the space or chamher 9, and having an inner edge portion adapted when the strip is adjusted, to be moved to the desired position with relation to the outer surface of the sash rail 10 The screws 15 permit the member 14 to be securely held in adjusted position.

In Fig. 6', I have shown still another modified construction of the improved ventilatingdevice. This construction is similar to that shown in Figs. 4 and 5, except that the deflecting portion of the device is omitted,

and the lower part 14 thereof is directed rearward in a horizontal plane, affording a ceases ticularly well adapted for use by reason of' the readiness and convenience with which it may be installed and of the efficiency with which the foul or vitiated air is dischargedtherefrom without liability of entry of rain, snow or dust, or of the production of drafts due to the entry of the external air, and it will also be obvious from the above description that the device is susceptible of. considerable change without material departure from the principles and spirit of the invention, and for this reason I do not desire to be understood as limiting myself to the precise formation and arrangement of the several parts of the device as herein set forth in carrying out my invention in practice.
